Synthesis of borocarbonitride nanosheets from biomass for enhanced charge separation and hydrogen production.

Borocarbonitride (BCN) materials have shown significant potential as photocatalysts for hydrogen production. However, traditional bulk BCN exhibits only moderate photocatalytic activity. In this study, we introduce an environmentally conscious and sustainable strategy utilizing biomass-derived carbon sources to synthesize BCN nanosheets.

Overcoming the Oxygen Dilemma in Photoredox Catalysis: Near-Infrared (NIR) Light-Triggered Peroxynitrite Generation for Antibacterial Applications.

The peroxynitrite anion (ONOO ) is closely associated with many diseases and the creation of ONOO donors is an essential means of understanding its pathophysiological functions. However, it is challenging to develop ONOO donors due to the difficulties in simultaneously producing highly reactive and short-lived nitric oxide (NO) and superoxide anion (O ⋅ ). Here, we report a novel strategy for constructing ONOO donors by combining near-infrared (NIR)-mediated type I photosensitization and photoredox catalysis.

Ultrasound-Mediated Release of Gaseous Signaling Molecules for Biomedical Applications.

Although nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H S) have been considered as notorious gas pollutants for decades, they are considered as endogenous gaseous signaling molecules (GSMs), which have been widely recognized for their important signaling functions and prominent medical applications in human physiology. To achieve local delivery of GSMs to optimize therapeutic efficacy and reduce systemic side effects, stimuli-responsive nanocarriers have been successfully developed. Among them, ultrasound is considered as an attractive theranostic modality that can be used to track drug carriers, trigger drug release, and improve drug deposition, etc.

Engineering macromolecular nanocarriers for local delivery of gaseous signaling molecules.

In addition to being notorious air pollutants, nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (HS) have also been known as endogenous gaseous signaling molecules (GSMs). These GSMs play critical roles in maintaining the homeostasis of living organisms. Importantly, the occurrence and development of many diseases such as inflammation and cancer are highly associated with the concentration changes of GSMs.
